Martin Grigorov resolved WICKET-6396.
-------------------------------------
Resolution: Won't Fix
It has never been a target to make IModel API as `java.util.Optional`.
Those methods could be implemented but they do not make any sense for Wicket.
If you have a good use case for any of them then we can reconsider and reopen!
> Model should provide other Optional's methods
